Oh joy! Under-carpet heating

I was going to blip the utterly bare Church with the floor boards freshly sanded. Then I heard that the heating elements were being installed, so I dashed to have a look.
The floor was covered in glue, then a thin foam mat was rolled out. Very fine copper wires were sick to the mat, and these are the heating elements.

I know that we are in sunny Australia, but in Winter, this Blue stone unheated Church gets so cold, that you can still see the priest's breath at 11 am after 3 services on a Sunday. I was thinking about claiming some longjohn's as a business expense, for I can't stand the cold.
I am very excited about the heating! Can you tell?
